Check Digit Verification of cas no

The CAS Registry Mumber 1195-91-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,9 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1195-91:
(6*1)+(5*1)+(4*9)+(3*5)+(2*9)+(1*1)=81
81 % 10 = 1
So 1195-91-1 is a valid CAS Registry Number.

Synthesis of some novel chloro-/aryl-substituted-5,5-dimethyl-2-cyclohexenones

HariPrasad, S.,Jeevan Chakravarthy, A. S.,Pavan, K. P.,Venkatesh, G. B.

, (2020)

Two novel structural isomers: the dihalo-5,5-dimethyl-2-cyclohexenones were synthesized. Regioselective Suzuki-Miyaura cross coupling reaction of the isomers with nine different aryl boronic acids afforded eighteen novel compounds: the 2-aryl-3-chloro-5,5-dimethyl-2-cyclohexenones and the 3-aryl-2-chloro-5,5-dimethyl-2-cyclohexenones in 90–95% yields, which were characterized spectroscopically by IR, NMR and MS. The single crystal X-Ray diffraction ORTEP views of four representative compounds unambiguously confirm the formation of substituted cyclohexenones.

A mild and environmentally acceptable synthetic protocol for chemoselective α-bromination of β-keto esters and 1,3-diketones

Khan, Abu T.,Goswami, Papori,Choudhury, Lokman H.

, p. 2751 - 2754 (2006)

A wide variety of unsubstituted β-keto esters can be brominated chemoselectively to the corresponding α-monobromo-β-keto esters by using a combination of vanadium pentoxide, hydrogen peroxide and ammonium bromide in a biphasic system, dichloromethane-wate

A quick, mild and efficient bromination using a CFBSA/KBr system

Jiang, Pan-Pan,Yang, Xian-Jin

, p. 90031 - 90034 (2016/10/09)

Bromination is a fundamental transformation in organic chemistry and brominated compounds as building blocks are of paramount importance in organic synthesis. In our study, we have developed an efficient method of bromination by using a CFBSA/KBr system at room temperature in a short reaction time. Notably, this approach has been proven to be applicable to a range of substrates including 1,3-diketones and β-keto esters, phenols, aromatic amines and heteroarenes with good to excellent yields.
